Method Detail

equals back to summary

equals	back to summary
public boolean equals(Object other) Implements abstract javax.el.Expression.equals. Doc from javax.el.Expression.equals. Determines whether the specified object is equal to this `Expression`. The result is `true` if and only if the argument is not `null`, is an `Expression` object that is the of the same type (`ValueExpression` or `MethodExpression`), and has an identical parsed representation. Note that two expressions can be equal if their expression Strings are different. For example, `${fn1:foo()}` and `${fn2:foo()}` are equal if their corresponding `FunctionMapper`s mapped `fn1:foo` and `fn2:foo` to the same method. Parameters other:Object the `Object` to test for equality. Returns:boolean `true` if `obj` equals this `Expression`; `false` otherwise.

public boolean equals(Object other)

Implements abstract javax.el.Expression.equals.

Doc from javax.el.Expression.equals.

Determines whether the specified object is equal to this Expression.

The result is true if and only if the argument is not null, is an Expression object that is the of the same type (ValueExpression or MethodExpression), and has an identical parsed representation.

Note that two expressions can be equal if their expression Strings are different. For example, ${fn1:foo()} and ${fn2:foo()} are equal if their corresponding FunctionMappers mapped fn1:foo and fn2:foo to the same method.

Parameters

other:Object: the Object to test for equality.

Returns:boolean

true if obj equals this Expression; false otherwise.

getDelimiterSyntax	back to summary
public String getDelimiterSyntax()

getExpressionString back to summary

getExpressionString	back to summary
public String getExpressionString() Implements abstract javax.el.Expression.getExpressionString. Doc from javax.el.Expression.getExpressionString. Returns the original String used to create this `Expression`, unmodified. This is used for debugging purposes but also for the purposes of comparison (e.g. to ensure the expression in a configuration file has not changed). This method does not provide sufficient information to re-create an expression. Two different expressions can have exactly the same expression string but different function mappings. Serialization should be used to save and restore the state of an `Expression`. Returns:String The original expression String.

public String getExpressionString()

Implements abstract javax.el.Expression.getExpressionString.

Doc from javax.el.Expression.getExpressionString.

Returns the original String used to create this Expression, unmodified.

This is used for debugging purposes but also for the purposes of comparison (e.g. to ensure the expression in a configuration file has not changed).

This method does not provide sufficient information to re-create an expression. Two different expressions can have exactly the same expression string but different function mappings. Serialization should be used to save and restore the state of an Expression.

Returns:String: The original expression String.

public MethodInfo getMethodInfo(ELContext context) throws ELException Implements abstract javax.el.MethodExpression.getMethodInfo. Doc from javax.el.MethodExpression.getMethodInfo. Evaluates the expression relative to the provided context, and returns information about the actual referenced method. Parameters context:ELContext The context of this evaluation Returns:MethodInfo an instance of `MethodInfo` containing information about the method the expression evaluated to. Exceptions ELException: if an exception was thrown while performing property or variable resolution. The thrown exception must be included as the cause property of this exception, if available.

public MethodInfo getMethodInfo(ELContext context) throws ELException

Parameters

context:ELContext: The context of this evaluation

Returns:MethodInfo

hashCode back to summary

hashCode	back to summary
public int hashCode() Implements abstract javax.el.Expression.hashCode. Doc from javax.el.Expression.hashCode. Returns the hash code for this `Expression`. See the note in the `equals` method on how two expressions can be equal if their expression Strings are different. Recall that if two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result. Implementations must take special note and implement `hashCode` correctly. Returns:int The hash code for this `Expression`.

Doc from javax.el.Expression.hashCode.

Returns the hash code for this Expression.

See the note in the equals method on how two expressions can be equal if their expression Strings are different.

If a String literal is specified as the expression, returns the String literal coerced to the expected return type of the method signature. An `ELException` is thrown if `expectedReturnType` is void or if the coercion of the String literal to the `expectedReturnType` yields an error (see Section "1.18 Type Conversion" of the EL specification). If not a String literal, evaluates the expression relative to the provided context, invokes the method that was found using the supplied parameters, and returns the result of the method invocation. Any parameters passed to this method is ignored if isLiteralText() or isParmetersProvided() is true. Parameters context:ELContext The context of this evaluation. params:Object[] The parameters to pass to the method, or `null` if no parameters. Returns:Object the result of the method invocation (`null` if the method has a `void` return type). Exceptions ELException: if a String literal is specified and expectedReturnType of the MethodExpression is void or if the coercion of the String literal to the expectedReturnType yields an error (see Section "1.18 Type Conversion"). if an exception was thrown while performing property or variable resolution. The thrown exception must be included as the cause property of this exception, if available. If the exception thrown is an `InvocationTargetException`, extract its `cause` and pass it to the `ELException` constructor.

An ELException is thrown if expectedReturnType is void or if the coercion of the String literal to the expectedReturnType yields an error (see Section "1.18 Type Conversion" of the EL specification). If not a String literal, evaluates the expression relative to the provided context, invokes the method that was found using the supplied parameters, and returns the result of the method invocation. Any parameters passed to this method is ignored if isLiteralText() or isParmetersProvided() is true.

params:Object[]: The parameters to pass to the method, or null if no parameters.

Returns:Object

if a String literal is specified and expectedReturnType of the MethodExpression is void or if the coercion of the String literal to the expectedReturnType yields an error (see Section "1.18 Type Conversion").
if an exception was thrown while performing property or variable resolution. The thrown exception must be included as the cause property of this exception, if available. If the exception thrown is an InvocationTargetException, extract its cause and pass it to the ELException constructor.
